My daughter feels better within 15 minutes of getting Hyland's Teething Tablets. I wish I'd had these for my first two!! I started using them with her first couple teeth around 5 months and she didn't like me putting them in her mouth. Now at 9 months when she sees one coming toward her she opens her mouth for it! I think she knows that they make her feel better! Her temp goes down, her running nose alleviates, and her crabbiness disappears!
You can find them at most drug and discount stores, but there are other homeopathic brands at stores like GNC/SuperSupplements also.
